Answer:
67
Step-by-step explanation:
There are 65 seats in row 20, option D is correct.
Given that number of seats in row 3 are 31.
Number of seats in row 6 are 37
We need to find the rate of increase, we can calculate the difference in the number of seats between row 6 and row 3 and divide it by the number of rows in between:
Rate of increase = (Number of seats in row 6 - Number of seats in row 3) / (6 - 3)
Rate of increase = (37 - 31) / (6 - 3)
Rate of increase = 2
So, the number of seats increases by 2 seats per row.
To find the number of seats in row 20, we can use the rate of increase:
Number of seats in row 20 = Number of seats in row 3 + (Rate of increase × (20 - 3))
Number of seats in row 20 = 31 + (2× (20 - 3))
= 31 + (2 × 17)
= 31 + 34
= 65
Therefore, there are 65 seats in row 20.

Answer:
he parameter h is the extremal point of the quadratic. The extremum happens when x=h, when the function (x−h)2 is minimized (or −(x−h)2 maximized). So the reason for the minus sign is because x=h is equivalent to x−h=0.

A truck can be rented from Company A for $90 a day plus $0.50 per mile. Company B charges $40 a day plus $0.60 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.
Tthe number of miles in a day at which the rental costs for Company A and Company B are the same is 500 miles
The truck is driven X miles per day
Charges of company A will be = 90+0.5x
Charges of company B will be =40+0.60x
We need to find the value of X when charges of both companies are same
90+0.5X= 40+0.60x
90-40 = 0.60x-0,50x
50 = 0.10x
50/0.10= X
X= 500
The charges of both companies will be same if truck is driven 500 miles per day

Find the derivative of f(x) = -4x2 + 11x at x = 10.
a) 19.5
b) -69
c) 30
d) -300
Answer:
-69 (Answer b)
Step-by-step explanation:
Apply the power rule for differentiation:
(d/dx){-4x^2 + 11x} = -8x + 11
Now substute 10 for x:
f '(x) = -8(10) + 11 = -80 + 11 = -69 (Answer b)
Answer:
b
Step-by-step explanation:
Using the power rule to differentiate each term
Given
f(x) = - 4x² + 11x , then
f'(x) = - 8x + 11
At x = 10
f'(10) = - 8(10) + 11 = - 80 + 11 = - 69 → b

Answer:
50ft
Step-by-step explanation:
Hi,
Considering that one side is equal to 38 degrees, we know this isn't a 30 - 60 - 90 triangle.
One of the legs is equal to 40 feet
So, tan(b) = 40/x
tan(38 degrees) is 0.78 round up to 0.8 (if that's what your teacher wants)
0.8 = 40/x
0.8x = 40
x = 50ft

Technology required. ABCD is a rectangle. Find the length of AC and the measures of a
and e.
Help pleaseee
Answer:
AC = 12.4
Theta = 75.96 degrees
Alpha = 14.04 degrees
Step-by-step explanation:
Mathematically, the angle at each edge of the rectangle is 90 degrees
So, we can see a right triangle ABC
Where AC is its hypotenuse
Mathematically, the square of the hypotenuse equals the sum of the squares of the two other sides
That will be;
3^2 + 12^2 = 9 + 144 = 153
AC = √153
AC = 12.4
We need to use the appropriate trigonometric ratio to get the value of alpha and theta
For theta;
Its opposite side is 3 while its adjacent is 12
The trigonometric ratio to use is the tan
so;
tan theta= 3/12
tan theta = 1/4
theta = tan^-1 0.25
theta = 14.04
Now for alpha, since we have a right triangle
theta will be 90-14.04
theta = 75.96
The measure of AC to the nearest hundredth is 12.37
SOH CAH TOA identityFrom the given figure, we have the following parameters
Using the theorem;
tan a = 12/3
tan a = 4
a = 75.96
theta = 90 - 75.96
theta = 14.03
For the length of AC, we will use the Pythagoras theorem
AC = √3² + 12²
AC = √9+144
AC = 12.37
Hence the measure of AC to the nearest hundredth is 12.37

The function f(x)=Acosh(Cx)+Bsinh(Cx). I need help determining the value of constant C>0 when the second derivative f''(x)=25(f(x)).
Answer:
C = 5.
Step-by-step explanation:
First, you need to remember that:
For the function:
h(x) = Sinh(k*x)
We have:
h'(x) = k*Cosh(k*x)
and for the Cosh function:
g(x) = Cosh(k*x)
g'(x) = k*Cosh(k*x).
Now let's go to our problem:
We have f(x) = A*cosh(C*x) + B*Sinh(C*x)
We want to find the value of C such that:
f''(x) = 25*f(x)
So let's derive f(x):
f'(x) = A*C*Sinh(C*x) + B*C*Cosh(C*x)
and again:
f''(x) = A*C*C*Cosh(C*x) + B*C*C*Sinh(C*x)
f''(x) = C^2*(A*cosh(C*x) + B*Sinh(C*x)) = C^2*f(x)
And we wanted to get:
f''(x) = 25*f(x) = C^2*f(x)
then:
25 = C^2
√25 = C
And because we know that C > 0, we take the positive solution of the square root, then:
C = 5
